Chapter 437: The Observatory’s Secret

The Observatory’s hidden entrance was a narrow maintenance door beside broken pipes. Aren crouched in front of it, comparing the markings with the map recovered from the garden.

Aren traced the markings with his finger. "The surveyors weren’t interested in dramatic entrances. They wanted to reach their equipment without climbing six flights of stairs."

Kai inspected the narrow doorway. "A shame. I wanted enormous doors and a welcoming committee."

Sera checked the straps on her equipment. "After the last welcoming committee tried to kill us, I think we can survive a disappointing door."

Lily arrived with the survey prism. The Nexus Association had approved their inspection, and two guards remained above.

Lily showed them the route chart. "I’ve copied the original map. We’ll stay inside the secured sections unless we can verify another passage. And nobody touches a control marked with a warning symbol."

Aren looked offended. "I know how to explore ruins."

Lily raised an eyebrow. "You tried to open three cabinets before I finished checking them yesterday."

Aren shrugged. "They were very interesting cabinets."

Kai smiled as he helped move the door. "Let’s find something interesting enough to justify the argument."

...

The passage descended beneath the Observatory’s main foundation. Old stone gave way to metal panels, and pale floor lights appeared as Lily activated the independent maintenance supply.

Aren paused at a junction, studying a circular emblem above the arch. "Observation division. This should lead to the expedition theater, not the central tower machinery."

Sera raised an eyebrow. "An expedition theater? What exactly were they watching down here?"

Aren examined the markings. "Aegis surveyors studied distant places before traveling. I assumed they used maps. Apparently, they had something better."

They passed through another door, and Kai stopped walking.

The chamber beyond was so enormous that the far wall vanished into darkness. Curved galleries rose around a circular platform, their railings shining like polished silver. Above them stretched a sky of thousands of stars, moving slowly across a deep blue vault.

A ring of light hung overhead. Constellations turned in opposite directions, tracing the courses of distant worlds. At the center of the chamber stood an immense lens, its glass surface holding an ocean of reflected starlight.

Sera walked to the railing. "I thought the garden was beautiful. This is something else entirely."

Aren looked upward, forgetting the notebook in his hand. "The builders made an entire sky for people who wanted to understand the world."

Lily examined the inactive consoles surrounding the platform. "They built it underground, away from weather. Each projection ring could display a different recorded view."

Kai watched a cluster of stars slowly separate into smaller points. "Now that’s an entrance worth finding. The disappointing door has been forgiven."

...

Lily opened the prism’s case on a stone desk. Its bronze rings rotated, projecting a blue model of the chamber. Several galleries appeared clearly, but a broad section of the western wall showed only broken lines.

Lily pointed toward the incomplete section. "The original survey map includes an upper observation platform. It’s beyond that collapsed section. The modern scans never reached it."

Aren pointed toward a broken stairway. "That used to be the direct route. The collapse cut it off."

Sera studied the drop beneath the stairs. "We’re not climbing across that. The support stones are hanging loose."

Kai studied a side passage on the chart. Its length and direction didn’t match the space around them.

He focused on Starbreaker. Worldline Navigation recognized an existing connection at a recessed arch beside the western gallery. The route folded through a short section of old spatial architecture and emerged beyond the collapsed wall.

Kai pointed toward the arch. "There’s another path. The prism can’t follow its shape, but Starbreaker recognizes the connection."

Lily moved beside him. "Does it show where the path ends?"

Kai nodded. "At the upper platform. It doesn’t tell me whether the floor there is intact, though."

Aren inspected the arch and found an old survey marker. "This was a service shortcut. The builders used a spatial connection to avoid running another staircase around the lens chamber."

Sera secured a rope to the railing and tested the stone beneath the arch. "Then we go slowly. Nobody takes a step until we’ve checked the next one."

The passage seemed ordinary until Kai noticed the stars ahead moving differently from those behind him. After several careful steps, the corridor curved around a corner that should have led back into the main chamber.

Instead, it opened onto the far side of the collapse.

Aren stared through the opening. "We crossed a distance the building has no room for. That’s an extraordinary piece of engineering."

Kai smiled. "We followed a connection that was already there. I’d rather not ask the architecture to do anything more ambitious."

Sera checked the platform before waving Lily forward. "Solid floor, intact railing, and a spectacular view. I’ll count that as a successful expedition so far."

...

The upper platform overlooked the entire celestial theater. Rows of seats curved around its edge, and an ancient viewing console stood beneath a transparent canopy.

Lily checked the console’s status. "The observation array is unavailable. Its external instruments are silent, and most stored files are damaged."

Aren’s shoulders fell slightly. "So we can’t see what’s out there now?"

Lily shook her head. "No, but some historical recordings survived. We can play those using the platform’s independent reserve power."

Kai rested a hand on the railing. "Then show us what they saw."

Lily selected the first readable entry. The stars above them dimmed, and the great lens filled with pale light.

A landscape appeared across the vault: an immense coastline where blue cliffs rose above an inland sea. White bridges connected islands suspended between the cliffs, and ships with shining sails moved through the air above the water.

Sera drew a slow breath. "That’s a real place? I can’t imagine what it must have been like to stand there."

Lily studied the recording details. "It’s a preserved survey image. We don’t know whether it still looks like this."

The view shifted. Mountains appeared beneath curtains of green light, their peaks encircled by enormous stone arches. Beyond them stretched a forest of trees so tall that clouds gathered among their branches.

Kai had seen extraordinary things during his battles, but this was different. Nobody was attacking them. They could simply stand and look at a world they had never known.

Aren stepped closer to the projection. "Wait. That arch on the northern peak. I’ve seen that design before."

He opened a copy of the expedition log recovered from the garden and turned several pages. An old sketch showed the same arrangement of three narrow supports around a circular opening.

Aren held up the sketch. "The log described it as a landmark used by western survey teams. I thought the drawing was symbolic. They were recording a real structure."

Lily placed the sketch beside the projected image. "The proportions match. That gives us a second source for the location, even if we don’t have a modern route to it."

Sera watched the landscape change again, revealing a city of pale towers beside a broad river. "Imagine growing up here and being able to see places like these whenever you wanted."

...

The next recording opened a map instead of a landscape.

Light spread across the chamber, forming continents, coastlines, mountain ranges, and hundreds of small survey marks. The map was incomplete, with missing sections flickering where the records had failed, but its scale made the Observatory seem suddenly small.

Aren compared it with the modern chart on his tablet. "Some of these coastlines don’t match any current map. Entire regions are missing from the records we use today."

Lily studied the differences. "That doesn’t mean they vanished. Borders change, and we don’t know how accurately they mapped everything. But these images are worth preserving."

Kai examined the distant survey marks. "At the very least, they knew about places we don’t. I wonder how far their explorers actually traveled."

Sera moved along the gallery, where the seats grew smaller toward the front. Several had little handholds carved into their sides, and one railing carried faded scratches shaped like stars.

She called Kai over. "Look at these seats. Children sat here."

Aren joined her and examined a plaque beside the seats. "Public instruction gallery. Students were brought here to learn geography and astronomy."

Sera smiled at the empty rows. "So this wasn’t only for expeditions. Families came here. Teachers probably had to stop children from climbing over the railings."

Kai imagined the chamber filled with excited voices beneath the artificial sky. "And someone had to explain why the stars moved when the lights were turned on."

Lily laughed softly. "I’d have been the child asking to see every recording twice."

Aren glanced at her. "You still are. Only now you have permission to operate the equipment."

Lily didn’t deny it. She was already copying the surviving images to isolated storage, checking each file before moving to the next.

...

When the final recording ended, the stars returned to their slow rotation.

Lily had recovered several usable geographic fragments and the Observatory’s old survey index. The prism now held a verified layout of the upper platform, including the service shortcut they had crossed.

Aren studied the index, then stopped on an entry linked to the expedition theater. "There’s a reference to the original field reports. The observation images were only summaries. The surveyors kept their full notes somewhere else."

Lily leaned closer. "Where did they store them?"

Aren turned the display toward them. A highlighted route ran from the Observatory’s lower foundation toward the Archive, ending at a chamber labeled Memory Access.

Aren enlarged the entry. "The reports were transferred here. If the chamber survived, it could explain where these images were taken and how the survey teams reached those places."

Sera glanced toward the fading landscape above the lens. "Then I’d like to know the stories behind them, not just their names."

Kai examined the marked route. "We already know the old passage connects Observation and Memory. Now we know exactly what we’re looking for when we reach the Archive."

Aren scrolled through the index and smiled. "There are hundreds of expedition entries listed here. If even a fraction survived, we could learn more about the ancient world than we have in years."

Kai looked once more at the artificial sky before turning toward the exit. "Then tomorrow we follow the route to Memory. I want to see what the people who traveled beyond this city wrote when they came home."
